I had Tolbert for the 2nd half of 20BH during Winter 2003. Surprisingly, I actually learned a lot from taking her class. Her lectures are usually interesting and well-organized but her homework and midterms are nightmarish. Half of the homework problems are written by her and these are the one's you MUST KNOW HOW TO DO -- she writes problems that force you to think so it's no longer the simple process of plug and chug. If you can't do these problems, you're screwed -- don't bother showing up for the midterms/final.

Overall, I would still say that Professor Tolbert is a decent professor. You will learn a lot from taking her class, but that may not necessarily be reflected in the grade you receive in her class.
